MACHINE FOR BEETLING CLOTH.

SPECIFICATION forming part of Letters Patent No. 387,749, dated August14, 1888.

Application filed December 1], 1983. Serial No. 114.927.

To aZZ whom it may concern.-

Be it known that 1, Duncan STEWART, a subject of the Queen of GreatBritain and Ireland, residing at Glasgow, in the county of Lanai-k,Scotland, have invented certain Int proveiuents in Machines for Beetling(.lloth, (for which I have obtained a patent in Great Britain, datedAugust 10, 1881, No. 3,462,) of which the following is aspecification.

My invention consists of an improved machine for the beetling,calendering, or finishing of woven fabrics, felt, paper, or yarn, ashereinafter described.

For the better understanding of the manner of using my improved machine,I have shown in the accompanying drawings, and have hereinafterdescribed, a number of accompanying devices which do not form anyessential part of my present invention, for the latter relates only tothe construction of the rotary beetlingcylinder itself.

Figurel n the aceompanyingshcet of drawings is a plan of the machinery,and Fig. 2 is a corresponding sectional elevation. Figs. 3 and 4 areenlarged sectional views of two modi fications of the spring-beetler.

My improved beetler is a shaft, 5, having on it a number of bands, 6,made of steel or other suitable elastic metal, bent each, as shown inFig. 8, into a spiral (volute-shaped) coil, or in an analogous manner,as shown in Fig. 4. The bands or coils G are fixed to the shaft 5 bymeans of their inner ends, on which ends dovetail pieces are formed orwelded, to be fastened by keys in dovetail sockets formed for them on aboss, 7, keyed on the shaft. The outer ends of the bands or coils 6 arefree to move to a certain extent, and have rounded striking-pieces 8formed or welded or otherwise fixed on them, and they are prevented fromflying out too far through centrifugal action when rotating by stop-pins9, fixed in disks or projecting plates 9, formed or fixed on the boss 7,these pins 9 acting on the extreme ends of the bands, as shown in Fig.3, or on loops, as shown in Fig. 4. The bands 5 are placed on the shaft5, so that their several ends are at difterent parts of the circle, andthe shaft being made to rotate at a considerable speed in the directionof the arrows, the ends of the bands tend to fly out by cen- (No model.)Patented in England Augusl 10,185], No. 24,402.

irifugal action, and in passing round strike the goods which aresuliijectcd to them. The goods pass round a roller, it), placed parallelto the beetler shaft The beetler bands or springs (3 may be from two tofour inches broad.

The action of the 'beetler is capable of being varied through aconsiderable range by varying the speed of rotation and the distancebetween the beetler-shaft 5 and the roller 10, on which the goods aresupported while being operated on.

The beetler-shaft 5 and the roller 10 may be mounted and driven in themanner shown in the drawings. The parts are carried on a framingconsisting of a pair of parallel side frames, 11, bolted down to asuitable foundation and connected by tie-rods 32, Figs. 1 and 2.

The beetler-shaft 5 is held in bearing-blocks 12, which are adjustablehorizontally on the tops of the frames 11. The adjustment of bothbearing-blocks 12 is effected simultaneously by means of ahand-wheel,13, on a small horizontal shaft, 14.,having on it worms 18ingear with worm-wheels 14: on screw-spindles 15, which act on thebearing-blocks. A'guard, 16, (not shown in Fig. 1,) is placed over thebeetler-bands 6, to prevent anything from getting improperly intocontact with them.

The beetler-shaft 5 has on one end of it fast and loose pulleys 17,for adriving-belt from an overhead shaft, and on the other end of it there isa pulley, 18, for a belt for driving a shaft, 19, below. A worm, 19,Fig. 1, on the low shaft 19, gears with a worm-wheel, 20, on a verticalshaft, 21, which, by means of bevelwheels 22, drives the roller 10,round which the fabrics pass while being acted on by the beetler. Thelow shaft 19 has also on it a small pulley, 23, for a belt, 23, whichdrives a grooved rollerfli. The grooves are arranged spirally and run inopposite directions from the center, so that as the roller turns it hasthe effect of breadthening or smoothing out the fabric as it is goingupon the roller 10.

The fabric to be operated on passes round two other rollers, 25 26,besides the one 10 which presents it to the action of the beetler, thethree rollers being at the angles of the triangle arranged so that thefabric incloses a space, 27, descending from the roller 10 to a roller,

25, beneath the flooring 33, thence proceed ing vertically upward to thethird roller, 26, and returning downward again to the roller 10. Thefabric is first entered from the inclosed space 27, and passing beneathbreadthener'bars 28 and in contact with the breadthener-roller 24,hereinbefore referred to, proceeds round the outer side of the roller10. The fabric is led round the three rollers 10, 25, and 26 two, three,or more times, so as to form as many plies or thicknesses on the roller10, each part being in this way operated on several times, each timewith fewer thicknesses outside of it, and receiving the final action ofthe beetler directly on it while having other thicknesses acting as acushion under it. The

fabric finally passes round a guide-roller, 29, to swinging foldingmechanism 30, of a wellknown kind, which deposits it in a folded pile,31.

In the drawings I have shown the folding mechanism as consisting of apendent swinging frame, 34, carrying at its lower'end guiderollers 35for the fabric, and being connected at its upper end by a rod or rods,36, to acrank or cranks, 37, on the driving-shaft 38, which imparts avibrating motion to the frame to fold the cloth back and forth inlayers.

I claim as my invention The rotating spring-beetler consisting of ashaft carrying elastic metal bands bent into coiled or similar form, anddisks or plates carrying stops for the outer ends of the bent bands,substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
